  • NUCLEIC ACID SIMULTANEOUSLY INHIBITING EXPRESSION OF MTOR GENE AND STAT3 GENE
    Publication number: 20210054378
    Abstract: The present invention relates to a nucleic acid molecule simultaneously inhibiting the expression of mTOR gene and STAT3 gene, and an anticancer pharmaceutical composition comprising the same. More specifically, base-paired siRNA or shRNA of the present invention, designed to simultaneously inhibit the expression of cancer-related mTOR gene and STAT3 gene in order to surmount the problem that siRNA or shRNA does not achieve high therapeutic effects due to the target specificity thereof, has the effect of promoting the death of cancer cells. In addition, the nucleic acid has the effect of synergistically enhancing the apoptosis of cancer cells when used in combination with an anticancer agent, finding useful applications as an anticancer composition or anticancer aid against various carcinomas.

  • OVERHEIGHT VEHICLES IMPACT AVOIDANCE AND INCIDENT DETECTION SYSTEM
    Publication number: 20200391761
    Abstract: A system and method are disclosed for overheight vehicle impact avoidance and incident detection. A detection subsystem of the system determines whether an incoming vehicle is clear to pass, depending at least on its height. The detection subsystem relies on distance sensors located along the freeway to detect the highest point of the vehicle and outputs an indication of whether the vehicle can pass. A warning subsystem receives the indication that a vehicle is overheight and provides a warning indication to the driver about the vehicle's inability to pass an upcoming structure. The warning subsystem may also perform a variety of other tasks, such as, for example, logging a variety of information about the vehicle and the incident, sending data about the incident locally to a central command, and generating reports.
